An electric beard trimmer is a great tool for guys who are growing facial hair like a beard or goatee.

Short of trimming your facial hair manually with scissors I've tried it. Doesn't work a beard trimmer helps to ensure your facial hair is kept trimmed and neat and also ensure that it's symmetrical.

Beard trimmers tend to come with length selectors which enable you to select how long or short your facial hair gets trimmed. The good thing about this is that again, it helps to ensure that your facial hair is kept neat.

Plus it also enables you to try different lengths to see what works best and what looks best for you.

At the short end, beard trimmers tend to enable you to trim facial hair right down to stubble if you like that look, which is the setting I personally use for my goatee. I usually trim it once per week or so.

Depending on your facial structure and how your hair grows, you'll probably figure out through trial and error (and perhaps through comments from your significant other!) what suits you in terms of what sort of facial hair you go with.

Some guys pull off the beard or goatee look better than others and there are certainly a number of different styles you can try to see what you like.

With a beard trimmer, you can then minimize the amount of time to keep your facial hair neat.
